摘要： A welding wire comprising a flux core having a core composition alloyed with a combination of alloying elements is described. The alloying elements comprise Cr and N, wherein the flux core comprises between 10% and 50% of the total weight of the weld wire. A metal sheath encapsulates the flux core, wherein the metal sheath comprises between about 90% and 50% of the total weight of the welding wire and wherein the welding wire can be used in a welding process without destabilizing a welding arc. One of the applications of the wire and welding process of the present invention is hard surfacing of the steel mill rolls, which are hollow cylinders usually on continuous casters. As an example, the rolls welded by the wire and method of the present invention can have a diameter of about 12 inches or less. Additionally, a welding apparatus comprising a welding gun with a device for feeding an electrode into the welding gun is described. The corresponding welding process calls for gas shielding of the electrode to reduce spatter and smoke emission while creating a smooth weld bead surface requiring less grinding and finishing. The resulting weld deposit has enhanced resistance to pitting corrosion.
摘要翻译：描述了一种焊丝，其包括具有与合金元素的组合合金化的芯组成的焊剂芯。合金元素包括Cr和N，其中助焊剂芯包含焊丝总重量的10％至50％。金属护套封装药芯，其中金属护套包括焊丝总重量的约90％至50％，并且其中焊丝可用于焊接过程中而不会使焊接电弧不稳定。本发明的电线焊接方法的应用之一是通常在连续脚轮上的中空圆筒的钢轧辊的硬表面。作为示例，通过线焊接的辊和本发明的方法可以具有约12英寸或更小的直径。另外，描述了一种焊接装置，其包括具有用于将电极馈入焊枪的装置的焊枪。相应的焊接过程需要电极的气体屏蔽以减少飞溅和烟雾排放，同时产生平滑的焊道表面，需要较少的研磨和精加工。所产生的焊接沉积物具有增强的耐点腐蚀性。

摘要： Three adjustable electrodes (33a-33c) within a chamber (40) form a thermal plasma generating system (30). The electrodes (33a-33c) are positioned with a narrow gap at one portion and a wide gap at another portion to form a cone shape. The gap between the electrodes is adjusted to accommodate for wear on the electrodes (33a-33c). An electric arc is initiated at the narrowest point between two electrodes which moves over the length of the electrodes because of a magnetic field created by the arc and the forward motion of the injected stream. At the end of the electrodes, the arc is extinguished and another arc is initiated. The continuous are moving along the electrodes ionizes a working stream that is tangentially injected from three pneumatic rings (35a-35c) which provide improved mixing of the working stream for high quality thermal plasma. The thermal plasma exits through a narrow orifice (42).

摘要： Plasma is generated in a vacuum processing apparatus and a high-frequency voltage is applied to a lower electrode on which a wafer is placed. The high-frequency voltage applied to the lower electrode is subjected to periodical on-off modulation, the on-off duty ratio of which is determined for each wafer or each plurality of wafers, to carry out plasma processing on the wafer. As a result, in the plasma processing carried out on the wafer, the wafer is fabricated with a high degree of reproducibility by suppressing variations in fabricated-line dimension from wafer to wafer without decreasing the throughput.

摘要： A welding method that enables the joining of at least two dissimilar, metallic alloys to form a weld that is free of cracks is disclosed. The method incorporates a pure (99.00% minimum by weight) nickel fill-wire, integrally assembled into the joint between the two alloyed metals to be joined. The alloys joined by this method are an iron-based, low expansivity, gamma-prime strengthened superalloy (i.e., Incoloy®) and a high carbon, powder metallurgical tool steel high in refractory metal alloying agents (i.e., CPM REX 20). Welding of the joint results in the formation of a nickel rich region within the weld, thus “inoculating” the weld against cracks. The weld joint formed by the method of the present invention can be used in the fabrication of a rotating anode bearing shaft assembly for use in an x-ray generating device.

摘要： Shape of a long reach device, e.g., a welding torch, suitable for use within a portion of an object along a joint curve, e.g., a weld joint, is determined by dissecting the long reach device into a discrete number of portions, identifying ranges of movement between each of the portions, and discretizing the ranges of movement into a predetermined number of intervals. A total number of possible shapes is determined based on the total portions of the long reach device having the first movement range discretized into a predetermined number of intervals. A representation of the long reach device having one of the possible shapes is compared with the representation of the portion of the object. A possible shape is deemed acceptable if less than a predetermined portion of the representation of the long reach device interferes with the representation

摘要： A collection method for an at least partially ionised sample is provided in which the part of the sample to be collected is discharged using an electrical conductor and the discharge part of the sample then leaves the confines of a retaining magnetic field. The discharged part of the sample and the non-discharged part are separated as a result. The collector and collection method are particularly suitable for use with ion cyclotron resonance where different parts of the sample are provided with a higher energy level to other parts.

Apparatus according to the invention include a stud arc welding gun having a spacer at a distal end thereof, and a chuck adapted to receive a stud having a diameter of more than about ⅜ inch. A stud feeding device is coupled to the gun for automatically loading studs into the gun. The stud feeding device can include a bowl feeder and a stud feeding conduit via which studs are transferred from the bowl feeder to the stud gun. A gun positioning device, such as an arm of a robot, is coupled to the gun, and automatically positions the gun such that the spacer is against a receiving surface of the workpiece. A controller coupled to the stud gun initiates a stud arc welding process to arc weld the stud to the workpiece.
